 World-Wide Standardized Seismograph Network

The World-Wide Standardized Seismograph Network (WWSSN) was an important global initiative established to improve the detection and analysis of seismic activities around the world. Initiated in the 1960s, the WWSSN aimed to create a uniform system of seismograph stations that could reliably measure and record seismic waves produced by earthquakes, volcanic activity, and even nuclear detonations.
